St George Illawarra have become the first team in five years to go unbeaten through the opening six rounds of a season, adding insult to Cronulla's horror Friday the 13th in Wollongong. The Sharks' 40-20 loss to their local rivals was only one concern, with Andrew Fifita and Paul Gallen sweating on knee scans on Saturday ahead of potentially lengthy stints on the sidelines. There is particular concern over Fifita, who had his left knee in a brace amd was on crutches, sparking fears he may have damaged his anterior cruciate ligament putting his season in doubt. Wade Graham (hamstring) and Luke Lewis (knee) will join the pair for scans after minor injuries, cutting through their star-studded forward pack and leaving them with an empty bench by fulltime. Against the odds Cronulla fought back from a 28-10 deficit before giving the Dragons an almighty scare when Josh Dugan was denied a try that could have brought them back within two. Read more
